ZERO POINT INITIALIZATION
—
COMPLETED nTH AXIS
[Function]
This signal notifies that the basic machine coordinate system has been set (established) during
zero point initialization using the marked point alignment method in the absolute position detection
system.
[Operation]
This signal is valid when "TYPE" on the [ABS. POSI PARAM] screen is set to "2", and turns ON
when the basic machine coordinate system is set (established).
This signal will turn OFF if initialization is carried out again or if the power is turned ON again.
